# Time Series Completeness — Daily Sum Series + Explicit Missing-Value Fill

> Time Series Completeness — Daily Sum Series + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Analyzes daily time series completeness records and fills missing values using zero, mean, or median imputation, producing two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability time-series-completeness-daily-sum-series-explicit-missing-value-fill-3f06f031 -d '<json body>'
```

Example prompt: Can you run a daily sum series and missing-value fill analysis on my time series completeness data — I have about 50 rows with observed_points and expected_points per date, grouped into two dataset groups, and I want median imputation applied to observed_points?

## When to prefer this

Choose this endpoint when you need both a daily sum series completeness summary AND a missing-value imputation pass in a single call for up to 200 rows of time series data. It is ideal for offline/batch analytical use cases where the data is already collected and no live external lookup, prediction, or real-time monitoring is required. It offers a cost-effective two-report bundle at $0.01 USDC.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Invalid date format (must match YYYY-MM-DD pattern)
- Missing required fields (row_id, date, observed_points, expected_points) cause row-level errors
- Invalid fill method or field enum value causes a validation error
- Payment of 0.01 USDC not completed — endpoint returns 402 and declines to process

## How this service works

Time series completeness — Daily sum series + Explicit missing-value fill: Daily sum series + Explicit missing-value fill for supplied time series completeness records (observed_points, expected_points). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) a daily sum series report summarizing observed vs expected points per date and group, and (2) an explicit missing-value fill report where null or absent values in the chosen field (observed_points or expected_points) are replaced using the selected method (zero, mean, or median), covering up to 200 input rows.
